SNAP-LOCK FOR DOORS, GATES, AND THE LIKE.

Application filed October 17,1918.

To all whom it may concern.-

Be it known that we, THOMAS GERSHOM Pnornn'r and VILLIAM Rnnwoon BROWN,subjects of the King of Great Britain and Ireland, residing at 1216Queen street, Chippendale, in the State of New South Wales, Commonwealthof Australia, have invented new and useful Improvements in811111.),LOC1ZS for Doors, Gates, and the like, of which the followingis a specification.

This invention relates specially to snap locks for motor car doors butit is also applicable to other doors, gates, and the like.

The improved snap lock comprises three main parts, viz :a guide plate tobe inserted into the frame of the door, bolt working within theguideplate and a combined plate spring and handle to which the bolt isloosely attached.

In the accompanying drawings Figure l is a vertical section of a portionof a car door and body showing the lock in position; the frame of thelock and the strike plate are in section, but the looking bolt, thespring and the handle are in elevation.

Fig. 2 is a front view of the door slam.

Fig. 3 shows a plan of the locking bolt.

Fig. l a section of the locking bolt at J K, Fig. 1.

A is the door frame, 13 the body frame; the guide plate 0 is countersunkinto the frame of the door, the strike plate D for the locking end ofthe locking bolt is countersunk into the frame of the body.

Within the guide plate C is the locking bolt E, the front end of whichis V shaped and inclined, as at 0, so that the bolt shall give way whenit engages with a corresponding incline on the strike plate. Near therear end of the locking bolt, it is cut away, as at 7, to enable thespring F to pass through. The spring F consists of a plate twisted atright angles, and bent at the top to form a handle G, or it may beprovided at the top with a separate handle; it is fastened by screws Hto the door frame.

upper end of the spring protrudes through a slot gin the plate I securedto the door frame. A notch I: is cut in the spring to enable it to beplaced in position in the looking bolt.

The door being closed and locked by the locking bolt F, as shown in Fig.l, in order that it may be opened, it will be necessary to pull thehandle G back to the position shown in dotted lines in Fig. l. V

This movement will move thespring l to the position shown by the dottedlines, and with it will come the locking bolt E through which the springl passes loosely thus enabling the end of the bolt to accommodate itselfto the curvilinear movement of the spring.

All the parts comprised in this invention are reversible, and althoughthe point of the locking bolt is shown V shaped, we may use any othersuitably shaped point, with suitable slam plate to correspond.

i. In snap locks for mot-or car doors, gates and the like, a guideplate, a bolt slidable within the guide plate, and a plate spring foractuating the bolt, one end of the bolt being cut away at one sine toreceive and loosely retain the plate spring thereon.

2. In snap locks for motor car doors, gates and the like, a guide plate,a bolt slidable within the guide plate and provided with a recess in oneside thereof, the side walls of said recess being extended toward eachother to partially span the recess and a plate spring loosely fitted insaid recess so that said extensions confine the spring therein againstlateral displacement.

In testimony whereot we have signed our names to this specification inthe presence of two subscribing witnesses.
